ALBERT HOLDEN ILLINGWORTH, OF BRADFORD, ENGLAND.

SPECIFICATION forming part of Letters Patent N 0. 745,188, dated November 24, 1903.

Application filed September 23, 1901. Serial No. 76,176. (No modelJ T0 at whom it may concern:

Be it known that I, ALBERT HOLDEN IL- LINGWORTH, worsted-spinner,a subject of the King of Great Britain, residing at Whetley Mills, Brad ford, in the county of York, England, have invented certain new and useful Improvements inand Connected with Apparatus for Performing the Operations of D'offingin Cap Spinning, Twisting, Doubling, and Similar Machinery, (for which application has been made in Great Britain, No. 5,644, dated March 18, 1901,) of which the following is a specification.

This invention has reference to improvements in and relating to the operations of doffing in spinning, twisting, doubling, and similar machinery wherein caps are used.

In carrying out the present invention, the bobbins ready to receive the yarn having been placed in position on the spindles and the caps having been put in place by the mechanical means hereinafter described, the spinning,twisting, or like operation is performed, and when the bobbins have been properly filled and the machinery stopped mechanism is operated which seizes the caps, lifts or removes them off the spindles, and carries them out of the way. Other mechanism to be described then operates to grasp and remove from the spindles the full bobbins, places them on pegs, and the cap-removing mechanism in proper'sequence of the operations replaces these caps on the spindles over fresh bobbins, which are applied emptyon the tubes on the spindles. These fresh bobbins are so applied by means of levers or arms carried by slides working vertically in front of the frame or by similar mechanism adapted for the ready receipt of empty bobbins in suitable order and for the inversion and location thereof on the spindles.

The removal apparatds for the caps consists of a series of nippers or tongs operated by mechanism moved by hand or by connections from the driving parts and suitably timed. These nippers engage recesses or projections on the heads of the caps and retain the caps during removal and replacement.

A nipping arrangement,herein described as apair of jaws, is brought into and removed from engagementby their being mounted, respectively, on rods which slide in opposite divided with, say, four arms so shaped as tocatch the yarn and cause the same to be caught and twisted around the upper portion of the whirl whenever the yarn by the lowering of the doffing apparatus relatively to the spindles brings these threads (still connected to the full bobbins) within their path of rotation, the cutting or severing operation on the yarns between this point of twisting on the whirl and the bobbins being assisted by a severing-bar,which serves as a holding means or nip for the threads to be cut or broken. These rotatory yarn-catching plates arecarried round by the spindle-tube base, owing to stops or projections engaging openings formed in the catch-plates. This yarn or holding bar is brought into and, as required, kept in proper position to aid the revolving catch-plates in bringing about the severing of the threads about those two parts, except that the bar is removed during the time that the full bobbins are in the act of being removed by the nippers from the spindles, carried to the front, lowered with the doffingframe, and deposited on a series of pegs supported at adjusted distances apart on a bar carried by framing, which frame is raised to meet the oncoming full bobbins and when in position on the pegs is further raised, and

this further movement increases the strain on the yarns sufficient to bring about their severance. Afterward it is lowered to its resting position ready for the stripping of such full bobbins into a carrying-receptacle for removal by means of a chain and chaingearing operated by a hand-wheel, the movements being controlled by a pawl and ratchetwheel.

The nippers, tongs, or equivalent parts that seize and hold the caps may beoperated for their opening and closing motions by screw-motion arms, cam-surfaces, slides, or

other convenient means mounted on suitable supporting parts and manually or mechanically operated by connections from the driving parts, and in front of each pair of nippers or cap-holders is arranged a guard wire or piece designed to keep the yarns clear of the operation of these holders.

Figure 1 is a front elevation showing the arrangement of the various parts of the mechanism. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a section on the line A A, Fig. 1, to an enlarged scale. Fig. 4 shows one pair of cap-nippers in position when grasping and about to move the cap. Fig. 5 shows one of the caps raised ready for removal to the front position. Fig. 6 shows a cap removed to the front inclined position and locked therein. Fig. 7 is a plan view of a pair of cap-nippers and their actuating slides and lever. Fig. 8 is a front elevation of Fig. 7. Fig. 9 shows the same parts as Fig. 7, but in their open position. Fig. 10 shows a detail. Fig. 11 shows the position of bobbin-nippers prior to their opening and grasping a full bobbin. Fig. 12 shows a pair of bobbin-nippers moved forward and caused to close after they have been around a full bobbin. Fig. 13 shows a bobbin in the position it will occupy after it has been removed from the spindles. Fig. 14 shows a bobbin in the position it occupies when about to be released from the bobbin-nippers and to fall onto its peg on the receiving-frame. Fig. 15 is a front elevation of a pair of bobbinnippers,theirslides, and their actuating parts. Fig. 16 is a plan of Fig. 15. Fig. 17 shows the parts indicated in Fig. 15 in the open position. Fig. 18 shows a pair of bobbins on their spindles, the left-hand spindle being shown in front view and the right-hand spindle in section, and the yarn-severing plates and the hinged guards for same and other parts. Fig. 19 shows one of the bobbins and its supporting and operating parts in end view. Fig. 20 shows a plan of the severingplate and the projection from the whirls for rotating it. Fig. 21 shows an alternative construction of the head of a cap, and Fig. 22 shows aplan of the same. Fig. 23 shows a form of bobbin adapted for use with the improved apparatus described. Fig. 24 shows an under side view of the base of the bobbin, showing the projections which engage the pins of the whirl. Fig. 25 shows a part plan of guard for rotary yarn-catching plates. Fig. 26 shows the yarn in the first position for severing. Fig. 27 shows the second and last position for severing the yarn. Fig. 28 shows in plan View an alternative mechanism for operating the slide-bars which carry the nippers either for lifting the caps or the full bobbins, and Fig. 29 is a side view of the same.

Referring to Fig. 1, a is the main framing of the machine. 12 represents the bobbins,ofsubstantially usual form, carried on the spindles c, which spindles are mounted on the bars 0. d is the lifter-plate, which supports a washer d, a second .washer (Z and the whirl 06 From this whirl d upwardly project, say, two pins or pegs d, (see Fig. 18,) which pegs enter slots d in the catch-plate d, the curved arms or fingers of which serve to catch the yarn when brought within their path of revolution and bring such yarn into contact with the whirl, so as to be wound thereon. These whirls d are each driven in the usual manner by means of a tape or band (not shown) from the tin cylinder. These pegs 62 also serve by their passing into the recesses b 5 (see Figs. 18 and 20) in the base of the bobbin 61 to give rotary movement to the bobbin, (which bobbin preferably has inclined and squared teeth at its base, as shown in Figs. 23 and 24,) and thereby to the cap placed upon it; but ordinary-bobbins having plain slots may be used instead of this particular form of engaging teeth.

Each cap e (see Figs. 18 and 19) has formed at its head a recess a or (see Figs. 21 and 22) a projection, either of which means for obtaining a holding may be engaged by the nipping-jaws ff. These jaws ff (see Figs. 7, 8, 9) in series are mounted, f on the sliding barf and f on the like barf The barf runs the length of the machine and at intervals carries jaws f, which are opened and closed from or to their companion jaws f, said jawsf being similarly moved by the movements of the barf in the oppositedirections. These movements of the bars f f are derived from a lever-arm f through connectinglinksf andf and screwmotions, respectively connected to the bars. f is a spring connected to the link f and to the carrying-platef which spring has a constant tendency to draw back and forth the barf and forth and back the barf. .The spring f connected to the lever f and to the angle-plate f also has a like effect. f (see Figs. 7 and 8) is one of a series of brackets supporting the nipping mechanism and being themselves supported from and actuated by a horizontal rocking spindle f, carried in journalf in the cross-piecesf of the longitudinal framef. The rocking movement of this spindle f is effected by means of a handlef and this movement of the spindle places the nipping-jaws ff in position on either side of the cap-recess a, so that by the movement of the handle f described cap 6 may be grasped and the reverse rocking movement of the spindlef will lift the closed jaws, and with them the grasped cap e, and carry them into the tilted position. (Shown in Fig. 6.)

g is an angular swing-catch centered at g on the upper end of a standard 9 mounted on the framef, said catch serving to hold back the caps e and their holding parts until again released.

A set-screw h is provided to each bracket f, which screw serves to adjust the extent of movement of each bracket toward the caps e. A series of yarn guides or wires 2' are placed one above and projecting in front of each pair of cap-nippers ff, and these guides serve to keep the loose yarns from becoming'entangled in the cap-jaws, and thereby being broken. The caps 0 having been removed, as described, from their operative positions on the bobbins b, the cap-dotting mechanism carrying them is lowered to bring the full-bobbin-doffing nippers 7c into position opposite the bobbins b, these parts being carried by the frame f.

The nippers 7c is are placed one on either side of the full bobbin opposite them when in their open position, and they are brought toward each other and into contact with the filled bobbin 1) by the movements respectively in opposite directions longitudinally of the two flat bars k 10 carrying the nippers 7.: k.

The bar 70 is at its outwardly-bent end 70 (see Fig. 16) centered on the handle kiwhich lever 10 is centered at k to the carrying-plate W. The bent end is? of the bar k is in like manner centered at k to the opposite end of the handle-lever 10 The movement of this lever k in either direction gives an opposite move ment to the jaws k 70. The spring 70 or a screw motion normally tends to move the bars to close the jaws is k.

The movement horizontally back and forth of the bobbin-nippers It It is effected as follows: The bars 7.6 k are each formed with a hole, through which is passed the bolt 70 said bolt passing down and through the slot 10 in the backwardly-projecting carrying-V plate 70 and by its head 10 and the nut 15 holding those parts loosely in position, with capability of sliding to and fro. The movement of the bars from the position for engaging the jaws 7c is with the bobbin is effected by rocking the lever-arm Z of rockshaft Z, on which shaft is affixed a forked arm Z the fork of which embraces a pin 1 projecting laterally from the lug Z mounted adjustably on the bar 10 The rock-shaft Z, running the length of the machine, is mounted in bearings Z carried by the brackets m, one of which is seen in Fig. 15 mounted on the shaft m,which shaft is carried in bearings 07/ in hanging bars 01, attached to the framing f.

The bobbin-nipper parts and their operating-supports are normally kept out of operative position by means of a catch 0, mounted on a bar 0, said bar being centered at 0 on the frame Viewing Figs. 1 and 14, the row of pegs are spaced upon the bar 19 at appropriate distances apart corresponding to the distance apart of the spindle bobbins and caps and are guided in their up-and-down movements on that bar by the downwardly-projecting rods p therefrom sliding in other bars 0 p, supported by angle-pieces from the frame a.

The bobbin-nipper jaws, one of which, 70, is

seen in Fig. 14: with the full bobbins b be tween them, are brought down in the movement of the dofling-mechanism framef from the position shown in Fig. 13, and the jaws and bobbins are drawn forward away from the spindles by the forked arm Z and its cooperating parts into the position shown in Figrlt, and meanwhile the bar 10, with its pegs p, one'onlyot which is shown in Fig. 14, have been raised by anotherbar 12 connected to it and to the chain 19 said chain being drawn upon by its passing partly around a pulley p mounted on the harp and operated bya hand-wheel and ratchet and pawl. (Not shown.)

At each end of the frame a is mounted a curved guide-bar a, one of which is seen in Figs. 1, 2, and 3. These bars serve to guide the nippers k it correctly in their upward and downward movement'clear of the spinningrollers r by contact in their passage up and down with the bars k 10 Viewing Figs. 1, 18,19, 26, and 27, s is a wire guard mounted at its ends in smallbrackets 3, (shown in Figs. 1 and 19,) projecting upwardly from the lifterplate d,'said wire being located in front of the whirls d from end to end of the machine and serving as a guard to prevent loose yarn from becoming wound around the rapidly-rotating whirls d or adjacent parts.

The guard-plate t, (see Figs. 18, 19, and 25,) hinged at t to the plate 15 from the lifter-plate (1, also runs the length of the machine and serves to protect the operative from accidentally coming in contact with the rotatory plates d t is a fixed stop mounted on t which determines the extentol' movement ofthe hinged guardtinitsuppermostposition. Thisguardplate 15 is of L shape, and the flanged part 25 is notched or cut away at appropriate distances apart to clear the bobbins Z). (See e- The bar to (seen in Fig. 1) is carried by pivoted levers 20, located at opposite ends of the machine and centered at w to the arms from the framing a, one of said arms being seen at 10 Fig. 2. This bar to when in position below the rotatory plates d serves to deflect the yarn attached to the full bobbins and to the rollers of the spinning-frame, so as to bring them into correct position for the cutting or severing thereof and avoiding strain being put upon the yarns near the rollers, where little twist has been imparted to them and where they are consequently weak.

The framing f and the parts carried thereby are counterweighted by weights, (not shown,) the connections between the frame and the weights being hereinsho'wn as chains.

y, provided each with an adjusting-link or adjusting-screw p which are passed over'a pulley y, carried by shafting g mounted in bearings g in the framing a, one of such bearings beingshown in Fig. 1. This shaft that point, while the full bobbin 1) being raised puts a strain on said thread, which partly draws apart and partly severe the fibers constituting the thread. Before removing the full bobbins b from the spindles o the severing-barn; is swung from the position shown in Figs. 1, 26, and 27 to a new position practically at right angles to the old one, or it may rest on the same plane as the base of the machine. The full bobbins are then removed from the spindles c and placed on the pegs p, situated on the harp, which is in the position shown in Fig. 26. The bar to is then moved back to its original position, and it will be evident that it must come into contact with the yarn and nip it against the frame portion, (marked a,) as shown in Fig. 27. The wire guard s prevents the yarn from becoming entangled with the lower portion of the whirl (on which the tape runs) as it is being removed on the bobbins from the spindles c to the pegs p. The tin cylinder is then moved round by hand, causing the starplate 01 to revolve, (the guard-plate t being removed to the position shown by Fig. 18 before the full bobbins are taken from the spindles 0,) winding the yarn round the whirl d a few turns, as shown by Fig. 19. In addition to doing this it also increases the tension on the yarn between the yarn and the bar to; but it does not itself efiect or cause the severance. The frame containing the full bobbins b is then raised to the position shown by Fig. 27, which gradually increases the tension on the yarn (the yarn being nipped between the bar 10 and the frame a and immovable) until it becomes too great, at which point the yarn is severed.

Figs. 28 and 29 represent an alternative mode to that already described for operating the sliding bars which actuate the cap-nippers and the full-bobbin nippers, in which 1 indicates the screw mounted in bearings 2 and 3, the bearing 2 being adapted to receive the screw 1. In the bearing 3 the screwspindle fits loosely and is prevented from moving in a longitudinal direction by the collars 4 and 5. Motion is conveyed to the screw 1 by means of the end piece 6. The bearing 2 is provided with a downwardly-extending pin 2 fitting loosely in the slot 7 in a the lever 8, thus enabling it to be always in line with the bearing 3. The lever 8 is pivoted to the carrying-bracket 9 at 10 and the sliding bars at 11 and 12.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isi. In a spinning-machine, a cap having recesses, a whirl provided with projections to enter said recesses, a nipper for lifting the cap, means for actuating the nipper, and a wire guard serving to prevent the entrance of the yarn into said recesses.

2. In a spinning-frame, nipping-jaws in pairs cooperating to grasp the caps, lift them off the spindles, hold the caps during the doffing and replace the caps on the spindles after empty bobbins have been substituted for full bobbins, bars carrying the cooperating jaws and slidable toward and from each other, a lever, links connected with the lever at opposite sides of its fulcrum, and also with the respective bars whereby on the oscillation of the lever the bars will be oppositely operated, and springs also connected with the lever at opposite sides of its fulcrum.

3. In a spinning-frame, a plurality of pairs of cap-holding jaws, means to operate the same, a frame to support the nipping-jaws and their operating parts, means to raise and lower said parts, a plurality of bobbin-nipper jaws and means to operate them to and from the full bobbins, means to engage these jaws with the bobbins and lift them off the spindles, lower them onto a row of receiving-pegs and release the jaws in combination with a series of pegs, a supporting-bar for said pegs, means to raise and lower the peg-bar to meet the full bobbins.

4. In a doffing-motion fora spinning-frame, full-bobbin-nipping jaws, slide-bars carrying the jaws, means to operate the slide-bars in opposite directions and to open and close the jaws, means to raise and lower the jaws and full bobbins and 'a plurality of pegs to receive the full bobbins from the carrying-jaws, a peg-bar, peg-bar-carrying frame and means to raise and lower the pegs to and from the full-bobbin carriers.

5. Inaspinning-machine,a movably-mounted spinning-frame and a spinning-tube carried thereby combined with means connected wit-h the spinning-tube for moving the yarn out of its normal path, and a movable bar extending the length of the spinning-frame and adapted to press said yarn against the spindle-rail when said yarn is diverted from its normal path.

6. In a spinning-machine a guard mounted above the lifter-plate and in front of the whirl from end to end of the machine to prevent loose yarn becoming wound around the whirls and adjacent parts.
